Anyway. I am now convinced that underneath his heartless assasin mask, Hei is actually a big softie (with possibly a sister complex). I liked his interactions with Mao and Yin in this episode. And I was already squeeing last episode with him giving Yin the candy and asking Mao about the stars coming back (which seemed a rather personal question coming from him).
Maybe I'm hoping for too much, but I'd like a sort of camaraderie to develop between these three. Huang, not so much. Looks like he's going to try killing Yin next episode. :( Hei seems reluctant to do it himself, so I'm looking forward to see what he'll do next. I have to admit that Hei + Yin is pretty cute (in a platonic way). I think Hei's softened to Yin more since she grabbed his sleeve in episode 6. ...Well, at least it's more than just a "O_o GTFO" this time.
Also, that one Contractor who captures surveillance spectres and writes poetry as his payment was cool. And it's interesting how Hei and co. themselves are being targeted now. :O
EDIT: Chibi!Yin kept reminding me strongly of someone, and now I know who: Toph from Avatar LOL.
